Apparently, Jorge Mendes is involved in the transfer.
The Portuguese international will add goals and creativity to the midfield. He scores a lot more than the likes of Eriksen and Pochettino could use the extra goals from midfield.
The initial Tottenham offer was worth around €60m (€45m upfront plus €15m in bonuses) and Sporting are thought to be holding out for €70m (including add ons).
